Application inea November-e, i919. serial No. 335,997.-

Machine, of which t-he following isa speci` fication.

rlhe invention relates to an elevating machine, and more particularly to the class of grain, sand, gravel 0r the like handling, or loading machines. r

The primary object of the invention is the provision of a machine of this character, wherein grain, sand, gravel and other like substances can be elevated and delivered lat the poi-nt of deposit, without necessita-ting the hand pitching and slioveling of the sub# stance in the usual well known manner,- the machine being mobile so that it can be transported from one locality to another and Inotor propelled.

Another object of the invention is the provision of a machine of this character, wherein the elevating conveyer is mounted relative to the power wheel which also acts as a substance lifter, in a novel manner, so as to avoid any possibility of the piling of the substance or the overfiowiiig thereof during the exchange between the power wheel and said conveyer, thereby enabling the substance to be handled with dispatch and automatically during the working of the inachine, thus eliminating hand labor.

A further object ofthe invention is the provision of a machine of this character, wherein the po-wer wheel thereof is utilized as a part of the elevating mechanism, when the machine is at a standstill, the machine in its entirety 'being of novel construction and enabling the handling of substances expeditiously and without the use of hand labor.

The invention furthermore has for an additional object to improve machines of ther indicated character, in varying particulars` to the end that efficiency and operation may be promoted` as well as simplicity in constructionand convenience of adjustment and control.

The invention will be particularly explained in `the specific description following Reference isto be had to the accompany-V ing drawings forminga part of this specifi'- cation` in which similar characters of reference indicate corresponding partsv in all Figure l'is` 'aperspective lview of a niachine constructed in accordancewith the invention.

Figure 2 isa vertical longitudinal sectional view thereof.

Figure 3 is a vertical transverse sectional view taken tliiough vthe elevating conveyer.

In constructing a practical embodiment of the invention in accordance with the illustrated example, the frame 1() is provided. preferably comprising spaced parallel side beams or sills 11. which have forwardly convergent. end portions 1Q meeting each other and integrally joined together, while the rear ends of said side beams or sills 11 are.

united with a rear cross-axle 13 having adepending hanger 14 at oneend supporting ,awheel spindle 15 on which is journaled a.

relatively small ground wheel 1G, while the other end of said axle 13 terminates in a wheel spindle 17 on which is journaled a rela-tively large power and traction wheel 1S, the details of which willbe hereinafter fully described.

Rotatably mounted in the forward'end of the frame 10 is a vertical stearing post. column or stem 19, which has its lower end fixed in a wheel fork 2() having journaled therein a front guide wheel 21. the upper end portion of thepo'st, stem or column 19 being bent at right angles to forni a steering lever 22 which is adapted to be manually controlled for the guiding of the machine inv its tra-vel.

Supported on the frame l0 forwardly thereof is a motor 23, preferablyof the iiiternal combustion type, although any other form of motor can be'substitutediffound desirable, the driving 'shaft thereof carrying a belt wheel or 'pulley 24 over which is tra-ined a power transmiion belt the same being also trained over a belt wheel or pulley QG fixed on one'end of-a driven shaft 2T, the same being journaled in bearings 28 upon the frame 10. the said driven shaft heing disposed transversely of the latter and having on its opposite end a` belt wheel or i pulley.29 over which is trained a belt30 the saine being also trainedover a ,drum 31 carried by the power wheel 18 at'the outer side thereof.v 'In this manner the power of the engine or motor 23 will be transmitted directly tothe said power wheel 18 ,for the advancement'ofthe machine, the motor or engine 23 being controlled and regulated iii any ordinary well known ma-nner.

- The' power Wheel 18, which may be termed what is knownas a bucket wheel comprises a relatively broad-flat tire or iini 32 provided at suitablel intervals with traction cleats 33 and this tire oi' rini has secured thereto on the outer side a guard ringer annular flange 34 which cooperates with an inner ring or flange 35 to provide an annular space at the. inner periphery of said tire or rim,- the space being broken up into a plurality of buckets by means'of cross plates 36, whichextend between the outer and inner lrings or flanges.

v Mounted upon the rear laxle 13 and rising therefrom are spaced supporting yokes 37 and 38 respectively` the yoke 38 being of considerably greater height vthan the yoke 37 and on these yokes is v'mounted a transusual load sustaining cleats 41.

versely disposed laterally inclined conveyor frame 39am which is arranged an endless traveling conveyor apron 40, having the The frame 39 is tilted in the direction of the wheel 18 and extends therein to a point above the axis o'f'rotation thereof, the' apron 40 being driven from a roller142 having on one end of vits axle a 4belt wheel .or pulley 43 over which is trained an endless beltv44 the saine Y .being also trained over a belt Wheel or pulley 45 "fixed-to a countershaft 46 jouriialed longitudinallyiof the frame 10-in bearings 47. The counter-shaft 46 has fixed -thereto a bevel gear 49 meshing with a companion bevel gear 48 on the driven shaft 27, so that motion from the'inotor or engine 23 Will-be transmitted to the A apron 40 for the travel thereof in the conveyor frame 39 to elevate and deliver loads received from the bucket wheel Ain the operation of the machine and ,in a vmanner hereinafterfully described.

The lower endof the conveyor'franie 39 is formed with a hopper 5() having the upwardly divergent opposed side vvalls 51, which have'their upper edges terminating close to thebuckets in the Wheel 18 to positively receive the contents of these buckets i which contents are discharged into the hopper 50, thereby assuring the exchange of the full capacity o f the bucket into said hopper Without any possibilityof the overflowing or the loss of the substance in the elevation thereof during the working of the machine. f `j It will be observed that the outside. flange or ring 34 is disposed.. at an angle so as to deflect the substance 'Within the' bucket in` *the `wheel towards the hopper for the discharge of' the contents of' the buckets thereinto. the side walls of' the hopper being designed to prevent the piling ofthe substance during the elevating .period lin the opera* tion of the lmachine.

Detachably mounted upon the spindle 17 carrying the wheel 18 is a leg or prop 52 which is a frame work composed of bars of .steel or other metal of such a length as to allow jacking the `said ground Wheel 18' in raised position so as to clear the ground when the machine is at a standstill,` so that the said wheel 18 will serve to elevatematerial to the conveyor apron 40 when such material is delivered into the buckets in said wheel.` On the removal of the leg or prop 52 the-wheel 18 will serve as a ground or "traction wheel and constitute the power wheel of the machine.for its transportation from one point or locality to another.

l'n the operation of the machine when it is desired to advance the saine the povver p wheel 18 is brought in Contact Withthe ground and'on the starting of the motor the machine will travel to the desired location, the power `from the motor 23 being transmitted directly to the wheel 16 for the advancement of the machine and the traction cleats 33 preventing the wheel 18 from slipping upon the ground.

' When it is desired to utilize the machine for grain, sand, gravel or other material,the leg or prop 52 is mounted upon the spindle 17 and positioned so as to raise the Wheel 18, thereby rendering the machine immovaf ble and converting the power wheel 18 int'o a-bucket Wheel. the material being introduced into the buckets interiorly of said Wheel andon the rotation thereof the said material or contents of the buckets Will be discharged onto 'the `conveyor apron 40 which elevates the material and'delivers the same at the desired point of deposit and at an elevation. the machine being useful for loading granariesftruck or other load reused in this manner, the traction cleats 33 prevent material from banking about the .Wheel and Iso minimize resistance to its rointernal ceivers or carriers. :When the machine is portingsaid ange Wheeland frame in elevated position, whereby said Wheel can be i. utilized for loading material When the rane is Stationary, a transversely extending inclined conveyor, and supporting yokes therefor attached to said axle, said conveyor having a hopper at its lower end extending Within the body of the flange supporting Wheel.

In testimony whereof, hereunto affix my signature. f
